Impact Of Covid-19 Nationwide Lockdowns And Unlock Phases In India On River Water Quality Of Upper Part Of The Ganga River, Dhara Kakwani, Abha Kumari, Kumar Suranjit Prasad, Bablu Prasad

Applied Environmental Research

The river water quality index (RWQI) of the upper Ganga canal has been computed to assess the effect of lockdown and unlock phases lead down by COVID-19 in India. Geospatial distribution of RWQI from January 2019 to December 2021 in the study area revealed significant impacts of lockdown on water quality. However, unlock phases (post lockdown) have deteriorated water quality since August 2020 and reached to actual conditions of the river by August 2021. To evaluate the lockdown as a management strategy to clean the river, other factors were reviewed including rainfall data, migration, and other activities. The results revealed …

The More Severe Adverse Effect Of Alcohol In Fc Gamma Receptor Iib Deficient (Fcgrllb-/-) Lupus Mice Than In Wild-Type Due To The More Profound Responses Against Alcohol-Induced Leaky Gut, Phatcharapon Yiengwattananon

Chulalongkorn University Theses and Dissertations (Chula ETD)

Consuming alcoholic beverages is well-known to have a part in causing inflammation and obstructing the function of the digestive system, and it may lead to leaky intestines. However, the relationship between alcohol consumption and Systemic Lupus Erythematosus (SLE) remains a subject of controversy continued. In general, alcohol can promote intestinal bacterial dysbiosis and also result in endotoxin release by Gram-negative bacteria. This stimulates many immune cells to produce inflammatory cytokines in the gut. This study focuses on the inflammatory response effect of FcgRIIb-/- mice upon loss of FcgRIIb receptors in which alcohol-induced leaky gut can occur. In 8-week-old mice lacking …

Development Of A Chitosan Nano-Immersion Vaccine Against Aeromonas Veronii Infection In Red Tilapia (Oreochromis Sp.), Pimwarang Sukkarun

Chulalongkorn University Theses and Dissertations (Chula ETD)

Red tilapia (Oreochromis sp.) is a prominent freshwater fish in Thai aquaculture. It has long been afflicted by severe bacterial diseases, ulcerative syndrome, and hemorrhagic septicemia, primarily caused by Aeromonas veronii. Vaccination is a key strategy for control and prevention. In this study a chitosan nano-immersion vaccine has been developed using a nanoemulsion technique and surface modification method with chitosan polymers. The physicochemical properties, mucoadhesive properties, immune response assays, and vaccine efficacy were investigated. The results showed that the vaccine is spherical-shaped, nanometer-sized, and having monodispersed positive charge. The mucoadhesive characterization, observed by SEM and fluorescence microscope imaging, demonstrated that …

Development Of A Latex Agglutination Test Based On Vh Antibody Fragment For Detection Of Streptococcus Suis Serotype 2, Kiratika Chidkoksung

Chulalongkorn University Theses and Dissertations (Chula ETD)

Streptococcus suis serotype 2 (S. suis 2) is an important porcine pathogen that causes diseases in both swine and humans. For rapid S. suis 2 identification, a novel latex agglutination test (LAT) based on heavy-chain variable domain antibody (VH) was developed. Firstly, the soluble 47B3 VH antibody fragment from a phage display library, in which cysteine residues were engineered at the C-terminus, was expressed in Escherichia coli. The purified protein was then gently reduced to form monomeric soluble 47B3 VH subsequently used to coat with latex beads by means of site-specific conjugation. The detection sensitivity was found to be as …

Molecular Survey Of Enterocytozoon Bieneusi In Bat Feces Collected From Various Areas Of Thailand, Chatuthanai Savigamin

Chulalongkorn University Theses and Dissertations (Chula ETD)

Enterocytozoon bieneusi is a microsporidian pathogen that can cause gastrointestinal diseases such as chronic diarrhea, abdominal pain, and nausea in humans, particularly in immunocompromised individuals. This pathogen has been found in the feces of various animals, from wildlife to domestic animals, but there have been no reports of its detection in bats in Thailand. Given that bat feces are widely used as fertilizers in agriculture and that bat-infested caves are tourist destinations where people may encounter bat feces, there is a need to study the presence of Enterocytozoon bieneusi in bat feces in these areas. In this study, 16 out …

Synthesis Of Mixed Metal High Entropy Oxyhalide For Photocatalytic Degradation Of Tetracycline, Chakgrid Noomak

Chulalongkorn University Theses and Dissertations (Chula ETD)

High entropy materials (HEMs) are new types of materials that contain five or more elements. HEMs have been applied in various applications. It has been proven that HEMs with multielement can provide good structural stability. However, the application of HEMs in the field of photocatalytic has rarely been reported. Therefore, it is interesting to construct HEMs to be used as photocatalysts. In this work, we designed and fabricated a mixed metal high entropy halide (SrxBa1-xBiO2Br), a novel photocatalyst that contains five elements in the structure, by incorporating metals (Sr and Ba) into bismuth oxybromide material (BiOBr) to enhance their stability …

Diversity Of Blood-Sucking Insects And Vector-Borne Diseases In Pig Farms In Thailand, Kritsada Thongmeesee

Chulalongkorn University Theses and Dissertations (Chula ETD)

Vector-borne diseases (VBDs) have been recognized as important diseases in humans and animals across the globe. Blood-sucking insects, such as mosquitoes, tabanid flies, and stable flies may carry pathogens, transmit, and cause VBDs in hosts, including pigs. In Thailand, most of the pig farms have backyard system implying that pigs could be easily exposed to blood-sucking insects and lead to infection with vector-borne pathogens (hemoplasmas, Japanese encephalitis virus (JEV), and Trypanosoma (T.) evansi). However, the information about vector-borne pathogens in pigs in Thailand needs to be updated. The objectives of this dissertation were to study the occurrence and genetic diversity …

NAKHARA (Journal of Environmental Design and Planning)

The COVID-19 pandemic brought the world to a standstill, demonstrating the critical importance of preparedness and adaptation in the face of pandemics and epidemics. Pandemics and epidemics have been a persistent threat throughout human history, causing significant mortality and morbidity, as well as disrupting economies, societies, and politics. The COVID-19 pandemic, caused by the SARS-CoV-2 virus, had a profound impact on healthcare systems worldwide, leading to hospitals transforming into pandemic centers. This case study, conducted at Riphah International Hospital (RIH) in Islamabad, Pakistan, explores the transformation of an existing facility into a pandemic center, highlighting the challenges faced in managing …

Development Of Electrochemical Biosensor For Detection Of Thyroid–Stimulating Hormone, Kittirat Kitticharoenwiwat

Chulalongkorn University Theses and Dissertations (Chula ETD)

This dissertation focused on the development of electrochemical paper-based immunosensor for determining thyroid-stimulating hormone (TSH) using a label-free immunoassay. Thyroid-stimulating hormone is a pituitary hormone that stimulates the thyroid gland to produce thyroid hormones for the body’s metabolism. The current electrochemiluminescence method for determining TSH as a specific biomarker indicating congenital hypothyroidism (CHT) onset is unfortunately restricted to laboratory settings, thereby resulting in limited practical utilization, delayed diagnosis, and severe outcomes. Herein, we proposed a simple, rapid, portable, and sensitive electrochemical biosensor with a label-free format based on bovine serum albumin (BSA)/graphene oxide (GO) nanocomposite for TSH determination. Caboxylated GO …
